使用源码包安装的 Nginx 没办法使用 ”service nginx start” 或 ”/etc/init.d/nginx start” 进行操作和控制，所以写了以下的服务控制脚本。
可以使用的选项有：
start 启动
stop 停止
reload 重载
restart 重启
status 状态
test 检查配置文件
1、创建脚本文件并添加执行权限
| # touch /etc/init.d/nginx | |
| # chmod +x /etc/init.d/nginx |
2、编写脚本内容
| # chkconfig: - 85 15 | |
| # description: Nginx server control script | |
| # processname: nginx | |
| # config file: /usr/local/nginx/conf/nginx.conf | |
| # pid file: /usr/local/nginx/logs/nginx.pid | |
| # | |
| # eastmoney public tools | |
| # version: v1.0.0 | |
| # create by XuHoo, 2016-9-14 | |
| # | |
| # source function library | |
| . /etc/rc.d/init.d/functions | |
| NGINX_NAME="nginx" | |
| NGINX_PROG="/usr/local/sbin/nginx" | |
| NGINX_PID_FILE="/usr/local/nginx/logs/nginx.pid" | |
| NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf" | |
| NGINX_LOCK_FILE="/var/lock/subsys/nginx.lock" | |
| # check current user | |
| ["$USER" != "root" ] && exit 1 | |
| start() { | |
| status | |
| if [[$? -eq 0 ]]; then | |
| echo $"Nginx (PID $(cat $NGINX_PID_FILE)) already started." | |
| return 1 | |
| fi | |
| echo -n $"Starting $NGINX_NAME: " | |
| daemon $NGINX_PROG -c $NGINX_CONF_FILE | |
| retval=$? | |
| echo | |
| [$retval -eq 0 ] && touch $NGINX_LOCK_FILE | |
| return $retval | |
| } | |
| stop() { | |
| status | |
| if [[$? -eq 1 ]]; then | |
| echo "Nginx server already stopped." | |
| return 1 | |
| fi | |
| echo -n $"Stoping $NGINX_NAME: " | |
| killproc $NGINX_PROG | |
| retval=$? | |
| echo | |
| [$retval -eq 0 ] && rm -f $NGINX_LOCK_FILE | |
| return $retval | |
| } | |
| restart() { | |
| stop | |
| sleep 1 | |
| start | |
| retval=$? | |
| return $retval | |
| } | |
| reload() {echo -n $"Reloading $NGINX_NAME: " | |
| killproc $NGINX_PROG -HUP | |
| retval=$? | |
| echo | |
| return $retval | |
| } | |
| status() {netstat -anpt | grep "/nginx" | awk '{print $6}' &> /dev/null | |
| if [[$? -eq 0 ]]; then | |
| if [[-f $NGINX_LOCK_FILE]]; then | |
| return 0 | |
| else | |
| return 1 | |
| fi | |
| fi | |
| return 1 | |
| } | |
| _status() { | |
| status | |
| if [[$? -eq 0 ]]; then | |
| state=`netstat -anpt | grep "/nginx" | awk '{print $6}'` | |
| echo $"Nginx server status is: $state" | |
| else | |
| echo "Nginx server is not running" | |
| fi | |
| } | |
| test() {$NGINX_PROG -t -c $NGINX_CONF_FILE | |
| retval=$? | |
| return $retval | |
| } | |
| case "$1" in | |
| start) | |
| start | |
| ;; | |
| stop) | |
| stop | |
| ;; | |
| reload) | |
| reload | |
| ;; | |
| restart) | |
| restart | |
| ;; | |
| status) | |
| _status | |
| ;; | |
| test) | |
| test | |
| ;; | |
| *) | |
| echo "Usage: {start | stop | reload | restart | status | test}" | |
| exit 1 | |
| esac |
3、将脚本添加到系统服务并设置开机启动
| # chkconfig --add nginx | |
| # chkconfig --level 3 nginx on |
4、测试脚本是否能够执行
运行命令：service nginx start 或 /etc/init.d/nginx start
